How do I enable/disable one breakpoint from another breakpoint?

[mron]

I'm new to debugging with gdb/lldb. How do I enable a breakpoint after another breakpoint is hit?

Also, what are the different syntaxes for? /se /py /nat?

And how do I use the hit_count syntax? Where do I use:

operator :: = '<' | '<=' | '=' | '>=' | '>' | '%' 

hit_condition ::= operator number

The only way I can think of, is a pretty obscure feature in LLDB called, "named breakpoints".   There isn't much documentation online, but there is some built-in help in LLDB: try "help breakpoint name".  You could name a group of breakpoints, and then enable/disable them by attaching a command to the controlling breakpoint.   All of that will need to be done via LLDB commands, I am afraid - VSCode UI has no provisions for advanced features like this.

Please read the "Expressions" section in the manual.   I think it's all explained there.
